Chapter 2 Installing CNS NetFlow Collection Engine
Installing on a Solaris or HP-UX Platform
Step 9
If a previous installation was detected, you are prompted whether to use old configuration files or to
install new configuration files:
Please choose one of the following..
(1) Install new default configuration files
(Your existing configuration files have been saved in the
config/old subdirectory should you want to refer to them later)
(2) Retain existing configuration files
(New default configuration files will be saved with '.default'
extensions should you want to refer to them later)
Please choose: 1
If option
1
is selected, previous files are kept in the
NDC_DIR/config/old
subdirectory as indicated. If
option
2
is selected, new configuration files are saved with the
.default
suffix, and the previous
installation’s configuration files are retained.
a.
When upgrading to CNS Netflow Collection Engine, Release 5.0 from version 4 or earlier, the
previous configuration is not backwards compatible so this prompt is not displayed. A tool is
provided to assist the user with migrating their previous configuration. See
Appendix G, “CNS
NetFlow Collection Engine Migration Tools.”
[link] for additional details.
b.
When upgrading to CNS Netflow Collection Engine, Release 5.0.2 from version 5.0 or 5.0.1 and
option
2
is selected, a migration script is run to automatically migrate minor changes in the XML
configuration format for release 5.0.2. Before the migration, the following is displayed:
Preparing to migrate 5.0/5.0.1 configuration...
Please carefully note any instructions given during the migration
since some configuration options have changed in this release.
After the migration, the following is displayed:
Successfully migrated /opt/CSCOnfc/config/nfc-config.xml.
Please carefully note any instructions above regarding additional
configuration updates that might be needed.
In certain unusual cases, this can be preceded by additional information about a configuration
incompatibility that cannot be resolved automatically. In that case, refer to details about
configuration format updates introduced in CNS Netflow Collection Engine, Release 5.0.2 in the
Release Notes for Cisco CNS NetFlow Collection Engine, 5.0.2
.
Step 10
Ownership of all files under the install directory
/opt/CSCOnfc
is set to the user that was specified
earlier; group ownership is set to that user’s default group.
Setting file ownership...
Next, operating system-specific configuration is verified:
Checking platform config...
This includes verifying that the data segment size limit returned by
ulimit –d
is sufficient. If not, a
warning message is displayed, and you should consult the platform system administration guide to
determine how this value is updated. This value should be at least the maximum size specified for the
collector process as described at [link to memory tuning section of customizing chapter].
